BACKGROUND 1. Field

Various embodiments relate to an electronic device and a bandwidthadaptation-based power control method in an electronic device.

2. Related Art

To meet the demand for wireless data traffic, which has increased sincethe commercialization of 4G communication systems, efforts have beenmade to develop next-generation communication systems such as a 5Gcommunication system or a pre-5G communication system.

The 5G communication system is under consideration for implementationand use in new bands, for example, ultra-high-frequency (mmWave) bands(e.g., a 60 GHz band), as well as existing communication bands. Inaddition, in order to mitigate path loss of radio waves and increase thetransmission distance of radio waves, application of techniques such asbeamforming, massive multi-input multi-output (massive MIMO),full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, andlarge-scale antennas to 5G communication systems is under discussion.

Bandwidth adaptation, which is an example of a technology beingconsidered for application to next-generation communication systems, maybe a technique in which an electronic device may select and use thebandwidth of a transmission signal, based on bandwidth informationtransmitted from a base station.

The bandwidth information transmitted from the base station may includevarious bandwidths. For example, the bandwidth transmitted from the basestation may range from a low-frequency band to an ultra-high-frequencyband, and the electronic device may select a transmission bandwidthaccording to a bandwidth transmitted from the base station from amongthe low-frequency band to the ultra-high-frequency band, therebytransmitting a signal.

When transmitting a signal, the electronic device may amplify the powerof a transmission signal using a power amplifier. According to the priorart, when transmitting a signal, the electronic device may amplify thepower of a transmission signal in a determined power control moderegardless of the bandwidth transmitted from the base station. In thiscase, the determined power control mode may be inefficient for use withthe transmission bandwidth selected based on the bandwidth transmittedfrom the base station.

For example, in the case where the power control mode is determined tobe suitable for a low-frequency band rather than a high-frequency bandwhereas the bandwidth received from the base station is a high-frequencyband, the determined power control mode may be difficult to use for thetransmission bandwidth determined based on the bandwidth received fromthe base station.

Various embodiments may provide an electronic device capable ofcontrolling power supply to a power amplifier by selecting a powercontrol mode, based on the bandwidth of a transmission signal, which isdetermined based on bandwidth information transmitted from a basestation, and a bandwidth adaptation-based power control method.

Various embodiments may provide an electronic device capable ofcontrolling power supply to a power amplifier by selecting a powercontrol mode, based on the bandwidth of a transmission signal determinedbased on bandwidth information transmitted from a base station and thepower of the transmission signal, and a bandwidth adaptation-based powercontrol method.

Theelectronic device, may select and activate at least one of BWP3(numerology1) 632 and BWP3 (numerology2) 634, based on the numerologyinformation included in the bandwidth part configuration information onBWP3 (numerology 1) 632 and the bandwidth part configuration informationon BWP3 (numerology2) 634. For example, one of BWP3 (numerology1) 632and BWP3 (numerology2) 634 may be selected and activated based on one ofsubcarrier spacing (SCS) information, the type of cyclic prefix of OFDM(e.g., type indicating a normal cyclic prefix or an extended cyclicprefix), or the number of symbols (e.g., 7 symbols or 14 symbols)included in one slot, among numerology information included in thebandwidth part configuration information on BWP3 (numerology1) 632 andthe bandwidth part configuration information on BWP3 (numerology2) 634.

According to various embodiments, the electronic device may select a BWPto be activated from among a plurality of BWPs, based on the receptionof a radio resource control (RRC) signal from a base station, or mayselect a BWP to be activated based on activation/deactivationinformation included in at least one piece of bandwidth partconfiguration information among bandwidth part configuration informationon a plurality of BWPs. As another example, the electronic device mayselect a BWP to be activated based on the reception of downlink controlinformation (DCI) from a base station. As another example, theelectronic device may select a BWP to be activated based on thereception of MAC control element (MAC CE) from a base station.

According to an embodiment, in the case of using an RRC signal, the basestation may include information on frequency resources allocated fromthe network or at least one piece of BWP-related time information in theRRC signal, and may transmit the RRC signal.

If theinformation included in the DCI is the same as the BWP (e.g., BWP1 622)that is in the activated state, the electronic device may ignore the DCIvalue, and if information included in the DCI is different from BWP1 622that is in the activated state, the electronic device may change theactivated BWP1 622 to the BWP (e.g., BWP2 624) corresponding to theinformation included in the DCI, and may activate the same. For example,the electronic device may activate BWP2 624 a predetermined time (e.g.,the time in slot units or the time in subframe units) after thereception of the DCI.

According to an embodiment, in the case of using DCI, an indexindicating activation/deactivation may be included in the bandwidth partconfiguration information on the BWPs. The electronic device may selecta BWP to be activated based on the index. In an embodiment, indexes ofrespective BWPs included in the bandwidth part configuration informationmay be included.

FIGS. 7A and 7B are diagrams for explaining an ET mode and an APT modeaccording to various embodiments

Referring to FIG. 7A, an envelope tracking (ET) mode may be a mode inwhich a power amplifier (e.g., the power amplifier 230 in FIG. 2, the1^(st) to n^(th) power amplifiers 330-1 to 330-n in FIG. 3, or the1^(st) to n^(th) power amplifiers 430-1 to 430-n in FIG. 4)(hereinafter, the power amplifier 230 in FIG. 2 will be described by wayof example) amplifies the power of a transmission signal RF_OUTaccording to envelopes 74 of an output RF_OUT voltage VCC of atransmission signal 72. According to various embodiments, in the ETmode, a voltage is supplied to the power amplifier 230 to conform to theoutput of a transmission signal, so the power amplifier 230 may output atransmission signal amplified to have the envelope that is the mostsimilar to the envelope of the transmission signal. According to variousembodiments, the ET mode is a mode in which the voltage, which isfrequently changed according to the envelope of the transmission signal,is applied to the power amplifier 230, which may consume additionalcurrent for changing the voltage. For example, it may be efficient touse the ET mode in an environment where additional current consumptionis negligible. According to an embodiment, the ET mode may be used inthe case where the current reduction attributable to the usageefficiency of the power amplifier 230 is greater than the additionalcurrent consumed in changing the voltage due to the large output of thepower amplifier 230. According to various embodiments, it may beefficient to use the ET mode in the case where the power of thetransmission signal is greater than a threshold value (hereinafter alsoreferred to as a “second threshold value”). As another example, the ETmode may be used in a manner such that the transmission signal isamplified by reducing the range of fluctuation in voltage even if thereis a big change in the envelope of the transmission signal and such thatthe amplified transmission signal is compensated for by the amount ofreduction in the range of fluctuation in voltage. In this case, a methodof compensating for the transmission signal by the amount of fluctuationin voltage, such as digital pre-distortion (DPD) or the like, mayrequire a sufficiently wider bandwidth than the bandwidth of thetransmission signal. For example, if the bandwidth of a transmissionsignal is 60 Mhz, the DPD method may require a bandwidth of 200 Mhz ormore in order to compensate for the transmission signal by the amount offluctuation in voltage, and if the bandwidth of the transmission signalis 60 Mhz or more, it may require a bandwidth much greater than 200 Mhz.For example, it may be efficient to use the ET mode in the case wherethe bandwidth of the transmission signal is less than a threshold value(e.g., 60 MHz) (hereinafter also referred to as a “first thresholdvalue”).

Referring to FIG. 7B, an average power tracking (APT) mode may cause thepower amplifier 230 to amplify the power of a transmission signal RF_OUTaccording to the average 76 of the output RF_OUT voltage VCC of thetransmission signal 72. Although the usage efficiency of the poweramplifier 230 in the APT mode is lower than, for example, in the ET modebecause a change in the voltage applied to the power amplifier 230 isnot greater than the ET mode, the power generation efficiency in the APTmode may be higher, so the APT mode may be used to amplify the power ofthe transmission signal in an intermediate band. According to variousembodiments, the APT mode may be used in the case where it isinefficient to use the ET mode because the transmission bandwidth isgreater than the first threshold value or because the power of thetransmission signal is less than the second threshold value.

According to various embodiments, thesecond threshold value may be specified or changed based on theperformance of the communication processor or the power amplifier.

In operation 1080, the communication processor 410 may select a secondtracking mode as the ET mode or the APT mode, based at least partiallyon the third determination and the fourth determination. According tovarious embodiments, the communication processor 410 may select the ETmode if the carrier bandwidth part of the second transmission signaldoes not exceed a first threshold value and if the power of the secondtransmission signal exceeds a second threshold value. As anotherexample, the communication processor 410 may select the APT mode if thecarrier bandwidth part of the second transmission signal exceeds a firstthreshold value or if the power of the second transmission signal doesnot exceed a second threshold value.

In operation 1090, the communication processor 210 may adjust the powersupply to the second power amplifier, based on the selected secondtracking mode. According to various embodiments, if the selected mode isthe ET mode, the communication processor 410 may control a second supplymodulator (e.g., the second supply modulator 340-2 in FIG. 3 or thesecond supply modulator 440-2 in FIG. 4), based on the envelope of thetransmission signal, thereby adjusting the power supply to the poweramplifier. If the selected mode is the APT mode, the communicationprocessor 410 may control a second supply modulator (e.g., the secondsupply modulator in FIG. 3 or the second supply modulator in FIG. 4),based on the average value of the second transmission signal, therebyadjusting the power supply to the second power amplifier.

Although it is described by way of example that the communicationprocessor 410 selects the ET mode or the APT mode, based on the carrierbandwidth part and the power of the transmission signal, in the abovedescription, the communication processor 410 may select the ET mode orthe APT mode, based on the carrier bandwidth part, the power of thetransmission signal, and the actually used bandwidth.

According to anembodiment, the mapping table between carrier bandwidth parts and powersupply control modes may be configured in the communication processor410, or may be stored in a separate memory (e.g., the memory 130 in FIG.1). The communication processor 410 may obtain carrier bandwidth partinformation, for example, carrier bandwidth part configurationinformation, through RRC, DCI, MAC CE, or the like from the basestation, thereby activating the carrier bandwidth part forcommunication, and may configure a power supply mode, for example, atracking mode, corresponding to the activated carrier bandwidth partusing the mapping table.

The bypass mode may be a mode,for example, in which constant power is supplied regardless of thetransmission signal.

Referring to FIG. 11B, according to various embodiments, a plurality ofcarrier bandwidth parts and one power supply mode may be mapped.
